+0.0The percentile uses the official 1×/1.5×/2×/4× rarity multipliers and published 60/30/9/1 odds. It is an independent statistical estimate, not an official leaderboard or guarantee.
How it works
A transparent estimate—not fake precision.
The score converts each mine into its published earning multiplier: Rock 1×, Coal 1.5×, Gold 2× and Diamond 4×. Your average is compared with the 1.27× long-run expectation, with sample size included.
Small portfolios naturally swing more. A single Diamond within ten mines is far more unusual than one Diamond within several hundred. The normal approximation becomes more informative as the portfolio grows.
